RF Exposure Procedures and Equipment Authorization Policies
This document identifies certain RF exposure evaluation procedures and requirements and equipment
authorization policies for mobile and portable devices.
1
It replaces preceding versions of this KDB and
should be used in conjunction with other FCC policy and procedure documents.
2
Unless otherwise
specified, the power thresholds in this document are applied with respect to the source-based time-
averaged output power defined in §§ 2.1091(d)(2) and 2.1093(d)(5) of the rules. While certain
simultaneous transmission issues have been addressed in specific FCC test procedures, RF exposure
evaluation considerations for other product configurations are still necessary.

As products and
technologies continue to evolve, the FCC Laboratory should be contacted using the OET-Lab Knowledge
Database (www.fcc.gov/labhelp
) about additional procedures and specific test requirements.
1) General test requirements and specific FCC test procedures
a) When required, portable devices must be evaluated using the specific FCC test procedures, and
the SAR measurement techniques of OET Bulletin 65 Supplement C 01-01 and IEEE Std
1528-2003.
b) When routine evaluation is required for SAR and the output power is ≤ 60/f
(GHz)
mW, the test
reduction and test exclusion procedures given herein, or in KDB 616217 or KDB 648474, are
applicable.
4
c) Unless excluded by specific FCC test procedures, portable devices with output power > 60/f
(GHz)
mW shall include SAR data for equipment approval. The FCC Laboratory may be contacted if
SAR is expected to be very low, especially for devices below 300 MHz, to determine if SAR
evaluation is necessary.
5
d) When applicable, 802.11 a/b/g devices should be tested according to the antenna diversity
procedures in KDB 248227.
6
Contact the FCC Laboratory for antenna diversity test requirements,
such as MIMO and beam-forming, in other product configurations.
e) When the SAR procedures require multiple channels to be tested and the 1-g SAR for the highest
output channel is less than
1
RF exposure evaluation includes measurement or computatinal modeling of field strength, power density, or SAR for devices
subject to MPE or SAR limits. For mobile devices that are categorically excluded from routine evaluation, simple calculations
may be used to estimate the field strength or power density to determine minimal antenna-to-user separation distances.
2
Other equipment authorization policies and procedures include items in the TCB Exclusion List (KDB 628591), OET Bulletin
65 and Supplement C 01-01, procedures at FCC OET Measurement Techniques (www.fcc.gov/oet/ea/eameasurements.html
), and
in other KDB Publications (www.fcc.gov/labhelp
).

The specific FCC test procedures, identified by KDB Publication numbers, are available using links at the website
(www.fcc.gov/oet/ea/eameasurements.html
). SAR measurement procedures presently available from this website are those for
3GPP/3GPP2 devices (KDB 941225), 802.11 a/b/g devices (KDB 248227), laptop computers (KDB 616217) and cell phones
(KDB 648474) with multiple transmitters, 3 - 6 GHz devices (KDB 865664) and system accuracy verification (KDB 450824) .

See footnote 3, supra.
5
This provision applies to portable devices that are designed with large antenna-to-user separation distances such that the SAR is
expected to be < 0.2 W/kg at the specified operating frequency and power level.
